OBJECTIVE
This study addresses functional data, pain, and the reoperation rate in patients undergoing primary total knee arthroplasty (TKA) during which the patella was or was not replaced.
METHODS
Fifty-three knees were included, 18 with the patella replaced and 35 with the patella not replaced. WOMAC and SF-12 scores and knee pain were analyzed preoperatively and 3, 6, and 12 months after TKA. The reoperation rate was also evaluated.
RESULTS
Both groups presented significant improvement in WOMAC score and pain at all postoperative follow-up appointments. There was no significant difference between the groups in all evaluated variables. Two subjects in the group did not undergo patellar replacement due to complaints of anterior knee pain after arthroplasty. There was no difference between the groups in relation to the reoperation rate.
CONCLUSION
Patients receiving patellar replacement during TKA did exhibit significant differences in the rate of reoperation, function, or pain when compared to patients in which the patella was replaced.
目的
本研究探讨初次全膝关节置换术（TKA）中髌骨置换或未置换患者的功能数据、疼痛及再次手术率。
方法
纳入53例膝关节，其中18例髌骨被置换，35例髌骨未被置换。术前及TKA术后3个月、6个月和12个月分析WOMAC和SF - 12评分以及膝关节疼痛情况。还评估了再次手术率。
结果
两组在所有术后随访时WOMAC评分和疼痛均有显著改善。所有评估变量在两组间无显著差异。该组中有2名受试者因关节置换术后前膝疼痛主诉未进行髌骨置换。两组在再次手术率方面无差异。
结论
与未置换髌骨的患者相比，TKA期间接受髌骨置换的患者在再次手术率、功能或疼痛方面未表现出显著差异。
